I LOOSE-LEAF, BINDER.

Application -fi1ed October 20, 1922. Serial No. 595,711.

To all whom it may concern: I

- Be it known that I, GEORGE WASHINGTON NE MAN, a citizen of the United States,and

a resident of'the city of Chicago, in the .5 county of Cook and State of Illinois, have invented certain new and useful Improve-t ments in a Loose-Leaf Binder; and I do. hereby declare that the following is a full, clear, and exact description of the same, refs erence being had tov the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification. v I

This invention relates to a loose leaf binder of that type in which the upper cover is removably and adjustably latched tothe leaf-impaling lpost'srand it is an object of thisinvention to generally improve this type of binder and provide a' novel method of assembly,especially in relation to the actuating means. for opening and closing the binder With these and other objects in view,

which will become more apparent in the following. description and disclosures in the drawings, this inventioncomprises the novel mechanism and combinations hereinafter described and moreparticularly pointed out and defined in theappended claimsj i In the accompanying'drawings which illustratea preferred embodimentof this invention and in which 'similarreference'numerals refer to similar features in the different views: 7 j

Figure 7 is an enlarged fragmentary sect1on of the upper clamping member showing the method of securing the operator to the actuator. I r e As shown on the drawings: Inthe exemplification of this invention,

there is illustrated a binder in which the leaves are impaledupon a pair of spaced posts 1 which are suitably secured to the lower cover or to a clamping member hinged to the lower cover as is common in the art. The upper cover 2 is hinged to a hollow clamping member 3 preferably made of sheet metal with its ends closed by cap members 4. Suitable apertures are provided in this upper clamping member for receiving the impaling posts which are shown as extending therethrough.

Frictional latching mechanism is concealed in the hollow clamping member 3 for frictionally locking the same with its attached cover to .the impaling posts, and an actuator for unlatching or releasing said mechanism is also housed within said clamping member and operable by means of a stud or finger piece projecting through said clamping member.

The frictional latching mechanism for each post comprises an apertured lever 5 through which the post passes. 'In the present instance, the lever 5 is fulcrumed at an intermediate point and its two arms are inclined downwardly, so that the apertured armwill have an oblique position with respect to. the post in order to frictionally b ind against the same. The powerarm of said lever is yieldingly urged in its normal posi' tion for increasingthe obliquity of its apertured end for applying the frictional or' braking action to itsimpaling post. For accomplishing this purpose, the lever 5 is provided with a slot or aperture at its fulcrum point which fits over a projection 6 on a fulcrum which constitutes one side or wall of a small square box 7 or the like, in

which a coil spring 8 is housed, as shown in Figure 4, that bears upwardly against the power arm of the lever, and normally forces the apertured end downwardly, thuswise in? creasing its obliquity with relation to the post for frictionally latching or binding the same to the upper clamping member. Each small box is provided with spaced apertures 9 in itsrbottom-as shown in Figurefi and the. bottom-.Otthe clamping membenis punched; upwardly into these apertures in order to nchorth e nr siti n- I11 hep t in structure illustrai fi i .o 109K P9 tioned beyond the; outer side ofits'postandthe lever extends inwardly, while theother foox 7 is positioned beyond the inner side of" HS post and its lever 5- ,eatencls o-outwardly his is for the purpose of allowing the acwator 1 1m ime ltan ensly; ct a e; -K.

The actuator consists of a'narrowrm etal plate having its ends bifurcated, or. provided-With spaced tines; adapted to. receive theimpaling posts 1 therebetween, The tines at one end ofthe actuator arebent upwardly near theirends and then slopedownwardly; to.provide. -.cams. 11, while; the tines at. the

The ELOtllfltOIflSOPQlftllgd by means oila semhly, the actuator .with a propersize hole in the ofliset portion; is properly pos t oned within the clampingmember,- the stud 12 is then inserted through-the slot '13, and its lower end. inserted in the aperture in: the off; set portion of the. actuator. The stud is preferably provided at itslower end with a reduced portion or neclrthat extends; some distance through the aperture for the, purpose of crimping or expandingflthesame over the adjacent surface of theactuatorby a tool insertable through the aperture 14:. in; the lower side of the clampingmember; The stud will accordingly be securely anchored to the actuator between the annular shoulder framed by the reduced neck and the swedged over end. It will of course be understood that the clamping member and its contained parts'are completely assembled before the sarne is applied to the binder.

The operation of the binderis clearly obvious and requires merely a shifting of the actuator to the right for unlocking or releasing the. leversiai by. raising; the. same against thetension-oiltheisprings 8. The leversmay be held in such released position by" the cams 11 and 11*, while the cover 1 is adjusted or removed. 7 When it is desired to again lock the cover in position, it is merely necessarytoshiitthe actuator to theleft to bring. the camsout of engagement" with the levers-,f5, Whentheisprings 8 will automatically ope1 "ate' v the levers into fric tiona-l engagement with the impaling posts;

It will accordingly be apparentthat'my an efficient and superior binder that can b'e readily assembled, and in which themetal partsmay be made oi light and th'n material 1 readily, stamped into shape, so that a lightl and; cheap structure;

may be produced; bu't one which isveryadu rable for'the service to which it isadapted:
